Chapter 1181: Practical Homework

The hot water showerhead, through a clean, non-bent straight hose, sprinkled slightly hot, clean water, drenching Jiang Yuan's skin until it turned bright red.

Being too tall, one encounters such problems in a fixed-temperature shower room. The solution is either to adapt or to sit down. But considering the stool might be stepped on by short people who are afraid of the cold, one can only bend over.

In Jiang Yuan's mind, the newly acquired Physicochemical Analysis (LV5) replayed like a revolving lantern.

Similar techniques in police schools usually appear in the form of criminal physicochemical identification. Academician Lou obviously had no expertise in this area, and what he provided was the most popular and comprehensive physicochemical analysis. The gold content of this thing is actually a bit too high, enough to support Jiang Yuan in establishing a separate inspection center.

Of course, in terms of knowledge monetization, physicochemical analysis may not be as good as cryptography. The benefits in computer-related fields are cliff-like ahead of other disciplines. But in terms of the scope of application in criminal-related fields, the value of physicochemical analysis is extremely high, and it can well make up for Jiang Yuan's shortcomings in the field of criminal science.

Especially since modern people are becoming more and more feminine. Not to mention that cases of female violent homicide are becoming fewer and fewer, men are becoming more and more afraid to use big knives and axes to kill people. They use thallium or pufferfish toxin at every turn. For these feminine cases, the assistance of physicochemical analysis will obviously be easier to solve.

Jiang Yuan washed for a long time, came out, used a little perfume, and changed into a new set of clothes.

"Senior brother is really handsome." Miao Ruixiang had already washed clean, and he had also woken up from the shock of being "taught on behalf of the master." He followed Jiang Yuan closely, praised him a few words, and then whispered: "Senior brother, you said that it is normal for me to learn some biology or something. It is not necessary to do physicochemical test papers, right?"

"Try it, do as much as you can." Jiang Yuan comforted his junior brother a little and said: "Bring the test papers back later, and we will do them together."

Miao Ruixiang was stunned: "Are you doing it too?"

"Well. I haven't done it for a long time, let's get familiar with it." After Jiang Yuan finished speaking, he said: "Help me contact Director Wan and make an appointment for a two-hour physicochemical laboratory. I have use for it."

Director Wan, Wan Baoming, is the director of the Changyang Criminal Science and Technology Center. The physicochemical laboratory in Changyang is also of first-class level, and it is more than enough for practice.

Miao Ruixiang didn't know why, so he scratched his head while agreeing. He thought that after graduation, there would be a completely different social life, but he didn't expect that after entering the Ningtai County Criminal Police Detachment, the difference could be so extreme.

Physicochemical laboratory.

Hearing that Jiang Yuan wanted to use it, Wan Baoming actively coordinated for Jiang Yuan and quickly found a gap for him to insert.

Yu Wenshu also called with concern and asked: "Jiang Yuan, if you have any problems here, you can find me. I am completely on your side."

He was worried that there would be any problems with the previous case. In Yu Wenshu's view, this is normal. After Jiang Yuan has done so many cases, how could there be no problems. The so-called "do more, make more mistakes," the criminal police industry is even more so. For a level like Yu Wenshu, making mistakes is not terrible, the key lies in how to handle the aftermath.

Jiang Yuan didn't understand these, and didn't hear Yu Wenshu's subtext, and casually shirked: "There is no problem at the moment, I am looking for Wei Shiyan and others to do some questions."

Yu Wenshu's expression became more serious. Is it necessary to use Wei Shiyan's background?

Even so, Yu Wenshu's expression tightened, and he said: "Jiang Yuan, still the same sentence, anything, you can find me. I will definitely help if I can, and I can think of ways to help you if it is not easy to help. If there is something, don't carry it alone."

Jiang Yuan heard the problem and hesitated: "There is no big deal, I mainly want to train Wei Shiyan."

"Hey, is that so?" Yu Wenshu said a few more words uncertainly. After ending the call with Jiang Yuan, he thought about it and dialed Huang Qiangmin's mobile phone.

Sometimes, cunning and fierce crocodiles are also useful.

Jiang Yuan didn't know how fancy the old criminal police thought. In the physicochemical laboratory, after getting familiar with various instruments, he waited for Miao Ruixiang and Wei Shiyan.

"Let's do the questions first." Jiang Yuan didn't give them time to greet, and let Wang Chuanxing distribute the test papers to the two.

"You can flip through books, but you can't check mobile phones. Chuanxing, you are responsible for invigilation and grading." Jiang Yuan said, sat down, took a set of test papers the same as Miao Ruixiang, and looked at them.

Miao Ruixiang and Wei Shiyan looked at each other and felt that the future was bleak.

Wei Shiyan always said whatever he had. At this time, he spread his body and said: "Master. Can't we just learn technology directly? What is the use of this theoretical thing, and it has been so many years since graduation, who will still do questions. Junior uncle is a little better, he just graduated, my graduation time is still early, and I didn't do many questions when I was in school..."

Jiang Yuan ignored him, put down the test paper in his hand, took out a pen, and started doing it, almost without gaps.

He has a cheat, and he is not qualified to say anything about Wei Shiyan. Now doing questions is also to confirm his ability. However, if Wei Shiyan wants to learn technology, he must follow his plan.

Simply learning a little technology and training an LV2 image investigator is a very easy thing for Jiang Yuan, but it is meaningless. Anyone who is willing to work hard, can persist in fighting, plus a little bit of opportunity, preferably with a little bit of talent, and then with the blessing of time and practice, has the possibility of reaching the LV2 level.

And Jiang Yuan currently masters multiple LV5 and LV6 image investigation technologies. To pass them down, mathematical foundation is indispensable.

Wei Shiyan is a good technical expert reserve. He is interested in solving cases, most importantly, he can endure his temper, is willing to work on the front line, plus his family background is good, no worries, the rest, just need to learn mathematics, which is relatively simple.

It is better than those who learn for a few years and then go for management positions or job transfers.

Of course, the probability of Wei Shiyan not learning it is also very high. But Jiang Yuan can only improve his lower limit, and has no interest in guaranteeing his lower limit.

Wei Shiyan felt a little wronged. Looking at Jiang Yuan's action of brushing questions, he couldn't help but want to back out in his heart.

In his life, although he has eaten chocolate that is more bitter than iced Americano, he has rarely encountered Jiang Yuan's attitude. I have to say, Wei Shiyan would rather...

"You check the answers." Jiang Yuan finished the physicochemical test paper and handed it to Wang Chuanxing.

Wang Chuanxing, who was dozing off, jumped up and looked at the time: "Finished so soon?"

"Try the test paper." Jiang Yuan gave a reason, took another math test paper and started doing it.

Wei Shiyan tilted his head slightly, and saw Wang Chuanxing holding a red pen, brushing check marks on the test paper Jiang Yuan just did.

Wei Shiyan looked at the answers prepared by Wang Chuanxing again, and they were indeed one-to-one, completely correct.

I have to say, Wei Shiyan suddenly felt that Jiang Yuan just now was very handsome, and urgently associated that if he was like this, like that, and then like this... Dad saw it, wouldn't he shout "Dragon gives birth to dragon, phoenix gives birth to phoenix, mouse's son will dig holes!" like before?

"This one." Jiang Yuan finished the math test paper and handed it to Wang Chuanxing.

A single test paper, he did it in less than ten minutes. This is something that normal math experts can't do.

Just like what Shing-Tung Yau said, many math problems are actually math games, not discussing math problems.

But the technology Jiang Yuan got from the system is different. It may not have such strong creativity, and it is not necessarily suitable for academic research, but whether it is the mainstream thinking of the discipline or random academic games, it is all included, which can be said to be detailed.

"Full marks!" Wang Chuanxing finished grading the test paper Jiang Yuan did, and gave Jiang Yuan a thumbs up for the first time.

"Good. You continue to invigilate." Jiang Yuan was also quite satisfied. The so-called learn math, physics and chemistry well, you can go anywhere without fear. He is now all-around in three subjects, and later he can directly calculate the shadow area of the criminal on paper.

Wei Shiyan saw Jiang Yuan start to fiddle with the instruments in the laboratory again, gritted his teeth, and started to do math hard...

Ten minutes later.

Not a single question was done.

Obviously, facing math, just being ruthless is useless.

Miao Ruixiang beside him was a serious student who passed the exam, and he was in a state of just graduating, barely able to write two questions. Looking back at Wei Shiyan's blank paper, he couldn't help but laugh and said: "Shiyan, your master allows you to check books, just learn and sell it now, do as many as you can, don't force it. Math, if you don't know, you don't know."

Wei Shiyan was in a state of thinking. Hearing Miao Ruixiang say this, he couldn't help but think deeply.

A moment later, Wei Shiyan got up and said: "Junior uncle, you are right!"

After speaking, Wei Shiyan said to Jiang Yuan: "Master, I want to study alone for a few days, make up for the foundation, and then come back to continue learning!"

After speaking, Wei Shiyan went out.

Miao Ruixiang was stunned, looked at Wang Chuanxing, and whispered: "Can't stand it?"

"Brahmin's thoughts, can't guess." Wang Chuanxing shook his head slightly.

Outside the door.

Wei Shiyan picked up his mobile phone and made a determined look of "Black Hat Hanging Monkey": "Mom, I want a tutor, math, the kind who is good at linear algebra." ===== CHAPTER 1182 =====
